Banking slowly left over the agricultural Lincolnshire countryside are the elite 'Red Arrows', Britain's prestigious Royal Air Force aerobatic team, who have commenced an In-Season Practice (ISP) training flight near their base at RAF Scampton. They turn at a gentle angle trailing white organic smoke before reforming in front of a local crowd at the airfield and working through a 25-minute series of display manoeuvres that are loved by thousands at summer air shows. Their objective is to appear perfectly spaced from a ground perspective. Freshly-ploughed English fields with properties, roads and hedgerows are seen below. After some time off, spare days like this are used to hone their manual aerobatic and piloting skills before re-joining the air show circuit. Since 1965 they've flown over 4,000 shows in 52 countries.
